In many states where GOP lawmakers have banned abortion, most residents say they support abortion rights in most or all cases, according to a survey published Thursday by the Public Religion Research Institute, a nonpartisan research organization that tracks views on abortion. In all, majorities of Americans in 43 states support legal abortion.

In the remaining seven states — South Dakota, Utah, Arkansas, Oklahoma, Idaho, Mississippi and Tennessee  — less than half of residents say abortion should be legal in all or most cases. These states are overwhelmingly Republican. 

Meanwhile, the proportion of Republicans who say abortion should be illegal in all cases dropped from 18% in March 2022 to 14% in December, according to the report, which was based on surveys of 22,984 Americans conducted between March and December 2022. The U.S. Supreme Court overturned Roe v. Wade in June.
